SLIDING WINDOW.

Application filed October 7, 1926. Serial No. 138,993

This invention relates particularly to the construction of an improved window frame for laterally sliding sash. v

The object of the invention is the provision of an inexpensively constructed window frame of the character above referred to which is adapted to be readily installed in a building, attractive in appearance, and efiicient in use.

More specific objects and advantages of the invention will appear in the following description.

The invention consists in novel construction, adaptation, and combination of parts hereinafter described and claimed.

In the drawing, 4

Figure 1 is a front elevation of a portion of a building containing a two-sash window embodying my invention. Fig. 2 is a similar view of a one-sash window. Fig. 3 is a vertical sectional view on lines 3-3 respectively of Figs. 1 and 2. Fig. 4 is a horizontal sec-'- tion on line 44 of Fig. 2. Fig. 5 is a plan view of the sill member for a one-sash window such as'illustrated in Figs. 2 and 4.

Referring to said drawing, my improved window frame comprises a sill member 10, a stool member 11, and a head member 12 all of Which are disposed horizontally, and vertical stile members such as 13 and 1414 Referring now to Figs. 2 to 5 inclusive, the sill member 10 is formed or arranged to provide an upper inclined surface or Wash 15 having a straight rear surface 16 and a stepped front surface disposed in two parallel planes 17 and 18 to afford the sill proper at the window opening and a relatively narrow tongue element 19 adapted to extend into the space between the outside boarding and the inside wall surface of the building.

The stool 11 is formed to provide a level upper surface 20 (Fig. 2) and with a rabbet in its under side to afford a surface 21 to engage against the rear surface 16 of the sill proper and provide a portion 22 to overlap the sill.

As illustrated in Fig. 3, the front edge 23 of the stool constitutes the rear stop surface for the sash S. For a single sash window, the head member 12 is in plan of a shape similar to that of the sill (Fig. 5) to provide a wide portion at the window opening and a narrower portion or tongue 12 to extend into the wall space at one side of the window opening.

The head member 12 is formed longitudinally thereof with a groove 24 into which extends the upper rail of the sash S, the inner surface 25 of said groove being dis osed in a plane with the stop surface 23 of t e stool.

Mounted upon the sill 10 and extending longitudinally thereof is a bar 26 which serves as a track rail for the sash by engaging in a way 27 provided in the under side of the bottom rail element 28 of the'sash S.

With a single sash window the stile. as 13, at one side of the frame is desirably formed of a single piece and is provided with a vertical recess 29 into which the adjacent sash stile 30 extends when the window is closed. The stile of the frame at the other side of the window opening is provided by two pieces 14 and 14 which are spaced at a distance apart canal to or slightly greater than the maximum thickness of the sash to permit the sash to be slided between the companion parts of the stile into the wall space at one side of the window opening.

The sash is represented in its closed position by full lines and in its full-open position by dotted lines S in Figs. 2 and 4.

The sash is removably held within the frame by the provision ofan outside stop 31 (Fig. 4) detachably connected to the stile part 14 the distance between the stile 1'3 and the stile part 14 being equal to or greater than the width of the sash.

Assuming the outside stop 31 is detached, the sash S is entered from the outside of the frame and shoved upwardly into the groove 24 to permit the bottom of the sash being passed over the track rail 26 sufliciently to enable it to enter the sash way 27, whereupon the sash is lowered into engaged relation with the track rail, and finally replacing and securing the outside stop 31 against the stile part 14 The construction of a window frame which will accommodate a plurality of sash in side by side relation will be understood from an inspection of Fig. 1 wherein I illustrate a window opening for two sash which are denoted by S and S, respectively. This construction differs from the one-sash construction in the provision of a tongue element as 19 at each end of the sill proper, which is denoted by 10 and by providing a tongue element 12 at each end of the head member 12.

Another difference from the single frame plaster and the window frame.

structure is in the use of two part frame stiles at both sides of the window opening.

A special feature of my invention consists in forming the frame stile elements 13 and 14 and the head member 12 each with a corner recess or rabbet 32 to receive backing boards 33 and also portions of trim-moulding 34 at the outside of the frame.

At the inside of the frame there is provided in the stile elements 13 and 14 and also in the head 12 a two step rabbet, the innermost step 35 serving as a backing support for the lath-and-plaster 36-37 internal surfacing of the building, the exposed surface 37 of the plaster being in a plane with the step 38 of the referred to rabbet.

Angle shaped trim-moulding 39 extend into the rabbets to cover the Joint between the The joining of the sill and head with the stiles of a frame should be done in a close fitting and secure manner to produce a rigid frame which is readily installed in the frame structure of a building, the frame studs, as 40 for example, are suitably spaced and cut to accommodate the window frame.

What I claim, is,-

- the frame.

2. A window frame comprising stiles, and a sill and head member secured to the lower and upper ends respectively of the stiles, said stiles and head member being provided with rabbets at the outer side of the frame for the reception of wall boards, said stiles and head member being each provided at the inner side of the frame with a two-step rabbet, the mner step thereof serving as a backing support for lath-and-plaster, and the outer surface of the other step being located in a plane to correspond with the exposed surface of the plaster.
